This refers to the computer systems used to control the overall environment. These
systems must perform the following tasks: generation of graphics for the display system,
computation of the state of the environment, control and interpretation of the input and
output devices. All of these tasks must be synchronized for each frame.
Several hardware configurations are currently used (in order of increasing
- a single graphics workstation where the one cpu does all of the tasks
- a single graphics workstation with multiple CPUs, with each being dedicated to a
- a graphics workstation with several graphics engines and several cpu's. Here there might
be two graphics engines, each dedicated to a single stereo view.
- a graphics workstation connected via a high speed network to a supercomputer that
performs the computations while the workstation performs the rendering
